Life-cycles

There are three things, and as the former are so will be the third:
Water flowing into the sea whence it came;
The line of a circle ending where it began;
And the soul of a living being returning to God whence it emanated...
Barddas

The disciples said to Jesus, "Tell us, how will our end come?" Jesus said, "Have you found the beginning, then, that you are looking for the end? You see, the end will be where the beginning is."
Gospel of Thomas Saying 18

The Cosmos is not wasteful: it is full of cycles of birth, growth, death and renewal. Nothing new comes into the system. What exists has existed since the dawn of time and will never be destroyed. It would not be surprising, therefore, to discover that the same holds true with our spirit / soul. This thought is expressed in the above extracts.
